Showers running inland from western coasts on strong to gale force W-NW'ly winds, extending into western Peak & Pennines. Local clusters giving frequent hail or hill snow, chance of thunder. Also risk snow for periods N & E Scotland, may move southwards. Much terrain stays frozen above 600-700m, but locally snow to lower elevations.
Cold, squally winds. Risk of snow, mostly morning.
Northwesterly, may change abruptly, often 20-30mph, some squally gusts over 40mph at times, perhaps 50-60mph eastern areas.
Beware of changing conditions: may be small at times, but risk of difficult walking and significant wind chill for periods.
Snow for a time
Risk an area of snow for an hour or more in the morning, focused on northern areas. Probably breaking up for a times into middle of day. Snow often falling to slopes, sometimes sleet or rain up to about 400-500m.
May persist higher tops
Cloud bases varied, often covering higher mountains above 800-1000m, lowering further in constant precipitation. Some breaks toward higher tops, mostly south and east of the Cairngorm plateau.
30%
Brief glimpses of sun. Visibility very good away from showers, but very poor in cloud and snow.
-2C. Wind chill in strongest winds below -15C on highest tops.
500 to 700m.

Prepare for marked wind chill and considerable buffeting early in the day, but conditions gradually easing.
Snow mostly north and east
Snow may affect the northern and eastern parts of the Cairngorms NP for a few hours, mostly flurries, possibly more persistent toward east for a time. Very little toward Ben Alder and Glen Garry.
Most persistent north/eastern areas
Varied cloud; around precipitation will be fairly extensive over the hills, lowest northern Cairngorms and around Lecht, in places below 700m. Some breaks to higher levels, best near/west of A9 and south from Dalwhinnie.

South veering westerly, often in the range 30 to 50mph, perhaps a brief lull.
Expect frequent buffeting across the hills, sometimes arduous walking conditions with significant wind chill.
Snow, later showers with hail
A period of snowfall is likely for a few hours, falling to lower slopes, extensive whiteout on hills. Tending to clear from west, later followed by showers with hail.
Fairly extensive
Shrouding the mountains most or all day, extensively during snow, to lower slopes in places. Bases may slowly rise from the west into the afternoon, then varied in and out of showers.
30%
Brief if any sun. Visibility very poor during precipitation, appalling if in snow and cloud, brief improvements lower terrain.
-2 to -4C, tending to slightly rise for a time.
Much terrain frozen following overnight frost. Becoming 300-400m perhaps slightly higher into early afternoon.
Most mountain terrain is likely to stay frozen throughout the week ahead. Sometimes freezing conditions to lower slopes, although some day-to-day variations. Wind speed and direction will vary considerably, intermittent lulls, but then a deep low is expected to affect Britain by Tuesday-Wednesday, bringing stormy conditions, perhaps widely. Further lows are likely to follow later in the week. Extensive snowfalls possible on the hills, a mix of snow and rain lower down.
